Description

Wastewater pumping station with odor blocking and odor treatment

The present invention relates to a wastewater relay pumping station that collects wastewater discarded from a house or factory and delivers it to a wastewater treatment plant spaced apart by a predetermined distance, and more particularly, by forcibly suctioning contaminated air filled in the pumping station and storing it in a tank. , As the internal pressure is lower than atmospheric pressure, it is possible to prevent the outflow of polluted air even if wastewater flows in, and by mixing the stored polluted air into the wastewater and transporting it to the wastewater treatment plant, the maintenance cost required for odor treatment can be significantly reduced. As the internal pressure of the pumping station is lower than atmospheric pressure, smooth inflow of wastewater can be expected. As clean outdoor air is automatically introduced, it is possible to prevent corrosion or oxidation of facilities by polluted air, as well as contamination during maintenance work. It relates to a wastewater relay pumping station that has both odor blocking and odor treatment functions that can prevent human accidents caused by air.

Usually, wastewater (sewage) discarded from a source such as a house, building, or factory goes through a process of neutralizing it with chemicals in a wastewater treatment plant, removing toxicity, and discharging it to the river.

Here, the wastewater treatment plant is built in a large area near the river, and a pumping plant that collects wastewater and delivers it to the wastewater treatment plant is built in the area farther away.

Such a pumping station is built in a state where a part is buried in a lowland or ground for smooth inflow of wastewater.

That is, as soon as the wastewater is filled to a predetermined level, it is pumped to the wastewater treatment plant.

However, due to wastewater, the pump station is always filled with polluted air containing odor.

In other words, when wastewater is introduced in this state, the polluted air is discharged to the outside as much as the volume of the wastewater to be filled.

Therefore, it has been pointed out as a cause of serious discomfort due to the occurrence of odor in the vicinity of the pumping station.

In addition, there is a serious problem that poses a risk to the life of a worker during internal maintenance due to various gases that cause odor inside the pumping station.

Recently, as part of solving this problem, a method of forcibly discharging internal contaminated air through a pump and purifying the discharged contaminated air with a filter has been proposed.

However, there is a problem that the overall treatment cost is excessively required as various chemicals, filtering materials, and electric devices are required to remove substances that are the cause of odors contained in contaminated air.

The present invention relates to a wastewater relay pumping station that collects wastewater thrown away from houses or factories and delivers it to a wastewater treatment plant spaced apart by a predetermined distance. As shown in FIG. 1, a concrete structure 10, a water pump 20, a compressor 30, and a controller It is a wastewater relay pumping station that combines the functions of blocking odor and treating odor with (40) as the main composition.

The concrete structure 10 is installed in a state where a part of the ground near a house or factory is exposed.

That is, the concrete structure 10 is constructed in a state in which the collection space S of the set volume through which wastewater flows into the inside is sealed with the outside, as shown in FIG. 1.

The concrete structure 10 is composed of a support 11, a supply pipe 12, a discharge pipe 13, and an air pipe 14.

The support 11 is mounted horizontally across the collection space S to mount the compressor 30.

The collection space (S) is divided into a lower side and an upper side by the support 11, and the portion except the compressor 30 is formed of a wire mesh so that the top and bottom communicate with each other.

The supply pipe 12 is installed in communication with the outside on the lower side of the collection space S, and wastewater is introduced into it.

The discharge pipe 13 is arranged in a T-shape in the center of the collection space S and is connected to the discharge port of the water pump 20 and the wastewater treatment plant, respectively.

That is, the lower end of the vertical pipe is connected to the outlet of the water pump 20, and the horizontal left end is connected to the mixing pipe 33 of the compressor 30 to be described later.

And the horizontal right end is connected to the wastewater treatment plant through the concrete structure (10).

Here, since the concrete structure 10 is located in a lower area than the wastewater treatment plant, the pipe connected to the wastewater treatment plant is mounted inclined upward.

The air pipe 14 is mounted on the upper side of the collection space S so as to be exposed to the ground so that external air is introduced.

Here, the inlet of the air pipe 14 exposed to the outside of the concrete structure 10 is mounted toward the ground to prevent the inflow of foreign substances.

At this time, a blower 15 that operates according to a signal from the controller 40 may be configured in the air pipe 14.

This blower 15 forcibly sucks external air and blows it into the collection space (S).

Here, the blower 15 may be configured to be replaceable with a filter for filtering foreign substances in the air passing through.

The supply pipe 12, the discharge pipe 13, and the air pipe 14 are provided with valves that regulate the flow path.

That is, the supply pipe 12 and the air pipe 14 are configured with a check valve to allow only the inflow of wastewater and external air into the collection space (S), and the discharge pipe 13 to allow only the discharge of wastewater.

Of course, it may be configured as a solenoid valve that opens and closes the flow path according to a signal from the controller 40.

The water pump 20 is disposed at the lower end of the concrete structure 10 as shown in FIG. 1, and pumps the wastewater flowing into the collection space S according to a signal to the wastewater treatment plant.

The water pump 20 has a suction port through which wastewater is sucked at a lower left side, and a discharge port through which the wastewater is discharged and a discharge pipe 13 is connected at the upper right side.

That is, the water pump 20 operates according to a signal from the controller 40 to pump the wastewater flowing into the collection space S to the discharge pipe 13.

Here, the water pump 20 is shown to be exposed to the collection space S, but may be independently configured in a space partitioned by a partition wall except for the suction port.

The compressor 30 is disposed on the concrete structure 10 as shown in FIG. 1, sucks contaminated air filled in the collection space S according to a signal, and mixes it into the wastewater pumped to the wastewater treatment plant.

Here, the compressor 30 is shown only to be installed inside the concrete structure 10, but may be installed outside the concrete structure 10 depending on the installation environment.

The compressor 30 is composed of a suction pump 31, an air chamber 32, a mixing pipe 33, and a bypass pipe 34.

The suction pump 31 sucks contaminated air filled in the collection space S according to a signal from the controller 40.

The suction pump 31 has a suction port through which air is sucked on the right side, and a pipe which is connected to the air chamber 32 and transfers the suctioned air is connected on the left side.

Of course, the pipe is equipped with a check valve that prevents backflow of air delivered to the air chamber 32.

The air chamber 32 is disposed on the left side of the suction pump 31 and serves as a buffer by compressing and storing the sucked contaminated air.

The air chamber 32 may be composed of a flexible air bag made of a material such as rubber, vinyl, coated fiber, or a large plastic box, a steel box, or a concrete box.

The mixing pipe 33 is connected to the discharge pipe 13 and the air chamber 32 in communication with each other, and supplies contaminated air stored in the air chamber 32 to the discharge pipe 13.

A plurality of check valves for preventing backflow of air are also installed in the mixing pipe 33.

The bypass pipe 34 does not supply contaminated air sucked by the suction pump 32 to the air chamber 32, but directly supplies the contaminated air to the mixing pipe 33.

A solenoid valve that opens and closes a flow path according to a signal from the controller 40 is mounted on the bypass pipe 34.

That is, when the suction pump 31 continuously operates due to the continuous inflow of wastewater, it is directly supplied to the mixing pipe 33 through the bypass pipe 34.

Accordingly, it is possible to minimize the load of the suction pump 31, thereby extending the life of the device and reducing energy required for operation.

At this time, one end of the mixing pipe 33 is branched into both prongs, and one is connected to the discharge pipe 13, and the other can be configured to be directly connected to an air purifier or wastewater treatment plant.

The controller 40 is disposed on the concrete structure 10 as shown in FIG. 1, and detects the internal/external air pressure and the level of wastewater flowing into the collection space S, and transmits an operation signal to the water pump 20 and the compressor 30. Print it out.

This controller 40 is composed of a positive water stop sensor 41, a positive water operation sensor 42, an internal pressure sensor 43, an external pressure sensor 44, and a control module 45.

The pumping stop sensor 41 and the pumping operation sensor 42 detect the lowest and highest water levels, and are mounted on the lower side of the collection space S and the bottom of the support 11, respectively.

The internal/external pressure sensors 43 and 44 measure air pressure, respectively, the internal pressure sensor 43 is mounted on the upper side of the collection space S, and the external pressure sensor 44 is a concrete structure 10 It is mounted to be exposed as an indicator on the outside of the unit.

The control module 45 is mounted on the upper side of the collection space S and outputs an operation signal to the water pump 20 and the compressor 30.

Hereinafter, an operation process of the pump station according to the present invention will be described.

First, as shown in FIG. 1, the water pump 20 cannot pump all the wastewater filled in the collection space S to the wastewater treatment plant, so that some wastewater remains.

Due to the remaining wastewater, the air filled in the empty space of the collection space (S) as shown in FIG. 2 is changed into polluted air that smells bad.

In this state, when wastewater flows into the supply pipe 12, the internal pressure increases as the water level in the collection space S rises, as shown in FIG. 3.

That is, when the internal pressure increases, the control module 45 operates the suction pump 31 as shown in FIG. 4 to suck the contaminated air in the collection space S, and compress the sucked contaminated air into the air chamber 32. Save it.

Therefore, as the internal pressure becomes lower than the external pressure, which is atmospheric pressure due to the compressed storage of the contaminated air, external clean air is automatically introduced through the air pipe 14 while preventing the outflow of contaminated air.

Subsequently, when the water level of the wastewater reaches the pumping operation sensor 42, which is the highest water level, the control module 45 operates the water pump 20 to discharge the wastewater filled in the collection space S through the discharge pipe 13 And send it to you.

Here, the contaminated air that has reached the maximum storage capacity of the air chamber 32 is automatically mixed into the discharge pipe 13 through the mixing pipe 33 as shown in FIG. 5.

That is, when contaminated air is supplied to the wastewater that is pumped to the discharge pipe 13, it is converted into air bubbles in the flowing wastewater and is discharged together with the wastewater treatment plant.

If the water level maintains the highest water level for a certain period of time due to continuous inflow of wastewater, the contaminated air sucked into the suction pump 31 is directly supplied to the mixing pipe 33 by opening the bypass pipe 34 as shown in FIG. 6.

Finally, when the water level of the wastewater reaches the pumping stop sensor 41, which is the lowest water level, the operation of the water pump 20 and the compressor 30 is stopped to maintain the standby state.

On the other hand, the contaminated air sucked into the suction pump 31 from the beginning is not sent to the air chamber 32, but can be directly supplied to the mixing pipe 33 through the bypass pipe 34. Therefore, the air chamber 32 may be omitted depending on conditions.

In addition, although it has been described that the compressor 30 is operated only when wastewater is introduced, it can be operated manually or independently at each setting cycle regardless of the inflow of wastewater.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and the present invention is not departing from the gist of the present invention claimed in the claims. Of course, various modifications may be implemented by those skilled in the art, and these modified embodiments should not be individually understood from the technical spirit or prospect of the present invention.
